处理图像时下载PHP文件

Question

I have the following script I think is making a file download instead of displaying text. This script is requested from another file as a function. After it does this anything echoed is downloaded.

If there is no echo an empty PHP file is downloaded.

Could someone please help.

Script:

<?php

function stickerCreate($serial,$location){
    ob_start();
    $header_image = "Content-type: image/png";
    header($header_image);
    $imgPath = 'sticker.png';
    $string = $serial;
    $directory = "serial_write/".$string.".png";
    $image = imagecreatefrompng($imgPath);
    $color = imagecolorallocate($image, 0, 0, 0);
    $font = 'arial.ttf';
    $fontSize = 18;
    $x = 300;
    $y = 480;
    imagettftext($image, $fontSize, 0, $x, $y, $color, $font, $location);

    imagepng($image, $directory);
    header_remove("Content-type");
    ob_flush();
}

?>

I dont know if it is the header that is doing it or what.

Thanks

Robert

Don't remove the header, so that browser will display the image normally.

<?php

function stickerCreate($serial,$location){
    ob_start();
    $header_image = "Content-type: image/png";
    header($header_image);
    $imgPath = 'sticker.png';
    $string = $serial;
    $directory = "serial_write/".$string.".png";
    $image = imagecreatefrompng($imgPath);
    $color = imagecolorallocate($image, 0, 0, 0);
    $font = 'arial.ttf';
    $fontSize = 18;
    $x = 300;
    $y = 480;
    imagettftext($image, $fontSize, 0, $x, $y, $color, $font, $location);

    imagepng($image, $directory);
    // header_remove("Content-type");
    ob_flush();
}

?>
